Wireless Transceiver Module 433M DC8‑25V VHF UHF Radio RF UA

Description:
1. WIRELESS TRANSMISSION: Users can use multiple wireless transmission modules for data transmission without laying too many long signal transmission lines
2. EASY TO USE: The module only needs to be powered on and connected to the RS485 equipment to realize data transmission between each other, which is very convenient
3. STABLE CONNECTION: You can operate the RS485 device at a remote end to prevent data transmission failure due to signal rust, broken connections, or poor contact
4. EASY TO OPERATE: The module only needs to set two parameters, which can be set through the dip switch, simplifying the parameter setting process, very user friendly
5. WORKING PRINCIPLE: The data signal received by RS485 can be converted into wireless signal, wireless communication in a certain distance and the other end of the wireless transmission module, the other end of the wireless transmission module to receive wireless signal, and then converted into RS485 signal output
